Abstract

A new and distinct cultivar of New Fuinea Impatiens plant named ‘Kibarbu’, characterized by its large soft orange-colored flowers; upright and compact growth habit; freely branching, dense and bushy plant habit; and dark green leaves.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name ‘Kibarbu’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program was to develop early-flowering varieties with numerous flowers, freely-branching and uniform plant habit, attractive flower and foliage colors, and good flower form.
The new cultivar originated from a cross made by the Inventor of the proprietary selection identified as W556 as the male, or pollen parent, with the proprietary selection identified as O22 as the female, or seed parent.
The cultivar ‘Kibarbu’ was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Gensingen, Germany, in April, 1997.
Asexual reproduction of the new cultivar by terminal cuttings taken at Gensingen, Germany, has shown that the unique features of this new cultivar are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kibarbu’. These characteristics in combination distinguish ‘Kibarbu’ as a new and distinct cultivar:
1. Large soft orange-colored flowers.
2. Upright and compact growth habit.
3. Freely branching, dense and bushy plant habit.
4. Dark green leaves.
Plants of the new cultivar can be compared to plants of the commercial cultivar ‘Xanthia’, disclosed in U.S. Plant Pat. No. 10,305. However, in side-by-side comparisons conducted in Encinitas, Calif., plants of the new cultivar differ from plants of the cultivar ‘Xanthia’ in the following characteristics:
1. Leaves of plants of the new cultivar are slightly smaller than leaves of plants of the cultivar ‘Xanthia’ and differ in vein color.
2. Flowers of plants of the new cultivar are a lighter orange color than flowers of plants of the cultivar ‘Xanthia’.
3. Plants of the new cultivar have slightly larger and flatter flowers than plants of the cultivar ‘Xanthia’.
A detailed comparison of plants of the cultivars ‘Kibarbu’ and ‘Xanthia’ appears in Chart A at the end of the specification.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph at the top of the sheet comprises a side perspective view of a typical plant of the cultivar ‘Kibarbu’.
The photograph at the bottom of the sheet comprises a comparison close-up view of typical flower buds, flowers and upper and lower surfaces of leaves of the cultivars ‘Kibarbu’ (left) and ‘Xanthia’ (right). Flower and foliage colors in the photographs may differ from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
Plants of the cultivar ‘Kibarbu’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in 25-cm hanging baskets in Encinitas, Calif., under commercial practice in a polyethylene-covered greenhouse with day temperatures averaging 23° C., night temperatures averaging 19° C., and light levels about 3,000 foot-candles. Plants were about 17 weeks old after planting a rooted cutting.
